- Smart Charging: 80A charger with customizable profiles for flooded, AGM, gel, or lithium-ion batteries. Features power factor correction, temperature compensation, and equalization stages to maximize battery life.
- Effortless Switching: 50A transfer relay automatically flips between inverter and AC input (shore or generator), with power sharing to avoid overloads.
- Stacking Flexibility: Parallel up to three units for 12kW or mix series/parallel for 240V split-phase setups, scaling power as your needs grow.
- Ignition Lockout: Ties into your vehicle's 12V signal to prevent idle drain, ideal for trucks and RVs.
Perfect Fit for Mobile and Off-Grid Lifestyles
RVers love its RV-C protocol for syncing with Victron or Magnum displays. Truckers anticipate J1939 support for fleet integration, while mariners gear up for NMEA 2000 compatibility. It's built tough for bumpy roads and salty air, with thermal protection and a wide operating range from 14°F to 140°F. Weighing in at 79.4 lbs and sized at 17.1" x 14" x 8.1", it mounts neatly in tight compartments.
Pro tip: Pair it with lithium batteries for silent, weight-efficient power. The configurable charger handles their unique curves, preventing overcharge while delivering fast replenishment after a day of heavy use.
